Last updated: April 2026 dataClassified under a single 10-digit line (2909110000), diethyl ether — also widely known as ethyl ether or simply ether — is a high-purity solvent and extraction agent used in pharmaceutical manufacturing, laboratory reagent applications, and as a starting material in organic synthesis. Mexico is the leading supplier to the US market, with India and Germany also significant sources. Because diethyl ether is a DEA List I chemical precursor, importers must comply with DEA registration and import permit requirements in addition to standard CBP entry procedures.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Diethyl ether is a DEA List I chemical, meaning importers must hold a valid DEA registration and obtain import permits for each shipment. Failure to comply can result in seizure and civil or criminal penalties, independent of CBP admissibility.
Beyond DEA permitting, diethyl ether is classified as a flammable liquid under DOT hazmat regulations, requiring proper UN packaging, hazmat labeling, and an accurate dangerous-goods declaration on the bill of lading. Ports may require advance notification for large-volume shipments.
